As shown in FIG. 1 to FIG. 2 , a compact egg-shaped propeller according to an embodiment of the present disclosure includes an outer shell 1, an inner shell 5, and a driving motor unit 2 arranged in the inner shell 5. The outer shell 1 is detachably connected to the inner shell 5. The outer shell 1 is egg-shaped. The outer shell 1 is provided with a front cover 1-1 at a top of the driving motor unit 2. The outer shell 1 is provided with a jet orifice 1-2 at a tail portion of the driving motor unit 2. Blades 2-1 are connected to one side of the driving motor unit 2 close to the front cover 1-1. The driving motor unit 2 is connected to a main control compartment 3. Foldable handles 3-1 are connected to a left side and right side of the main control compartment 3 respectively. The foldable handles 3-1 are movably connected to the inner shell 5.

In one specific embodiment of the present disclosure, the outer shell 1 is provided with a gap matched with the folding handles 3-1; and a handle lock catch 1-3 for fixing the folding handles 3-1 is arranged at a tail end of the gap.

In one specific embodiment of the present disclosure, start buttons are arranged on the folding handles 3-1.

In one specific embodiment of the present disclosure, a battery 2-2 is arranged in the driving motor unit 2; the battery 2-2 is connected with a motor; and the blades 2-1 are connected to the motor.

In one specific embodiment of the present disclosure, the driving motor unit 2 is provided with a supporting device 2-3 inside the inner shell 5.

In one specific embodiment of the present disclosure, the main control compartment 3 is fixedly mounted on the inner shell 5; and an upper part of the main control component 3 is provided with a battery indicator 3-2.

In one specific embodiment of the present disclosure, buoyancy blocks 3-3 are mounted on the left and right sides of the main control compartment 3; and the buoyancy blocks 3-3 are fixedly mounted on the inner shell 5.

In order to facilitate the understanding of the above technical solution of the present disclosure, the above technical solution of the present disclosure is described in detail below through specific use modes.

A compact egg-shaped propeller includes an outer shell 1, a driving motor unit 2 and a main control compartment 3.

All the components of the propeller are all symmetrically arranged along an axial direction. A battery 2-2 and a motor are in front and back arrangement at an axis. A front cover 1-1 will affect the water pushing efficiency. Adding the front cover 1-1 in front of blades 2-1 is to prevent debris and hands from entering. Since the front cover is arc-shaped, a user cannot touch the blades 2-1 even if the hands are thin enough to get in from certain positions.

The battery 2-2 is arranged at the back, which facilitates the user to take out the battery from the back.

The folding handles 3-1 of the propeller are held by two hands for operation. ON/OFF buttons are arranged on the folding handles 3-1. A signal will be sent to the main control compartment 3 if the ON/OFF buttons are pressed at the same time. The main control compartment 3 is connected to the battery 2-2 and the motor. At this time, the main control compartment 3 will supply power and an electrical signal to the motor to make the motor rotate to drive the blades 3-1 to rotate as well. After water is sucked from the front cover 1-1 and then pressurized, the water flows into an inner flowing channel 4. The water is then straightened through a supporting device 2-3 and is jetted from the jet orifice 1-1 at the tail, thus generating a thrust.

The folding handles 3-1 held by the two hands drive the user to move forwards in water. The battery indicator 3-2 can display the current battery power to the user. The buoyancy blocks 3-3 ensure that the whole device does not sink down and will float on the water after the user loosens the hands in water, facilitating search.

In specific use, according to the compact egg-shaped propeller of the present disclosure, the folding handles are held by the hands. The two folding handles pop up, and the start buttons are triggered. The battery starts to supply power. At this time, water flows through the front cover, is pressurized by the blades and supported by a supporting plate, and is finally jetted out from the tail of the inner flowing channel to generate a forward thrust. The egg model is also friendly.

After use, the handles are folded and are locked by the handle lock catch. At this time, the entire machine is like an egg. The buoyancy blocks provide enough buoyancy to the propeller in water, so that the propeller floats out of the water.

In summary, by virtue of the above technical solution of the present disclosure, by means of the layout, the gravity center is centered, the structure is compact and simple, and the appearance is simple and beautiful. The blades and the motor are designed in front, and the semi-circular front cover prevents debris and hands from entering. The battery is arranged at the back, facilitating a user to take out the battery from the back. The battery indicator can display current remaining power to the user. The buoyancy blocks ensure that the whole device does not sink down and will float on the water after the user loosens the hands in water, facilitating search. When the device is not in use, the handles can be folded, thereby facilitating storage and carrying.

The above is only the preferred embodiments of the present disclosure, and is not intended to limit the present disclosure. Any modifications, equivalent replacements and improvements that are made within the spirit and principle of the present disclosure shall fall within the protection scope of the present disclosure.
